EXAMPLE III
Referring to fig. 3, in the application of the first and second embodiments of the jig for replacing consumables of a grinding head to a robot, the robot further includes a robot arm 7.
The concrete process that the robot dismantles and treats to change bistrique consumptive material 3 does: the mounting seat 101 stops rotating, the mechanical arm 7 extends out of the polishing grinding head 10, the air blowing bamboo joint pipe starts air blowing at the moment, the vision system 4 is started, and in the implementation, the positioning area of the vision system 4 is as follows: the bottom end of the outer side of the L-shaped consumable seat 102, namely the outer end of the wedging groove 11 and the outer end of the grinding head consumable 3 to be replaced, the blowing bamboo joint at the moment after the vision system 4 catches the positioning area sweeps the position to blow away dirt at the position, so that the vision system 4 can further identify the positioning area and adjust the position of a pneumatic finger, meanwhile, the mechanical arm 7 pushes the cleaning sponge block to abut against the positioning area, and the pneumatic screwdriver drives the cleaning sponge block to clean the area to improve the positioning definition of the vision system 4; then, the mechanical arm 7 is driven to clamp the pneumatic finger bags on two sides of the to-be-replaced grinding-head consumable material 3, the center of the pneumatic finger is aligned with the center of the to-be-replaced grinding-head consumable material 3, the pneumatic finger is located above the consumable material disassembling component 2, it needs to be known that at the moment, at least part of the projection in the vertical direction of the pushing and knocking block 22 is overlapped but not overlapped with the L-shaped consumable material seat 102, and then the duplex cylinder pushes the pushing and knocking block 22 to knock the to-be-replaced grinding-head consumable material 3 towards the mounting seat 101.
The following two states can be adopted for the knock block 22 to knock the consumable 3 of the grinding head to be replaced:
firstly, the consumable grinding head 3 to be replaced is loosened by the knocking block 22 but is not completely separated from the wedge groove 11.
Accessible pneumatic finger presss from both sides tightly in the both sides of waiting to change bistrique consumptive material 3 this moment, and 7 drives to change bistrique for the consumptive material anchor clamps move to the middle part of mount pad 101, finally wait to change bistrique consumptive material 3 and drop from wedging groove 11, and final arm 7 will wait to change bistrique consumptive material 3 and place at the assigned position.
Secondly, the consumable grinding head 3 to be replaced falls off from the wedge groove 11 under the knocking of the pushing and knocking block 22.
The polishing grinding head 10 is provided with a conveyor belt, a consumable grinding head 3 to be replaced falls into the conveyor belt after falling off from the wedging groove 11, and the consumable grinding head 3 to be replaced is transferred through the conveyor belt; moreover, also can transfer the bistrique consumptive material 3 of waiting to change on the conveyer belt through pneumatic finger, and final arm 7 will be waited to change bistrique consumptive material 3 and place in the assigned position.
Further, after the consumable grinding head 3 to be replaced is detached from the wedge groove 11 and transferred, it is necessary to install the consumable grinding head 3 to be used in the wedge groove 11.
Specifically, refer to fig. 4, it places in tray 12 in order to use to wait to use bistrique consumptive material 3 to use through vision system 4 and advance line location to bistrique consumptive material 3, arm 7 moves so that pneumatic finger clamp gets the both sides of waiting to use bistrique consumptive material 3, will wait to use the installation face adjustment of bistrique consumptive material 3 and wedging groove 11 bottom surface butt to put horizontal position and regard as the top surface of waiting to use bistrique consumptive material 3 this moment, will wait to use bistrique consumptive material 3 to insert in wedging groove 11 from the inner of wedging groove 11 after, pneumatic finger will wait to use bistrique consumptive material 3 to loosen the back, arm 7 withdraws from polishing bistrique 10 bottom, this moment, can start the mount pad rotation, wait to use bistrique consumptive material 3 in wedging groove 11 with the big outer end is interior under the effect of centrifugal force, more than just accomplish the change of whole bistrique consumptive material 3.
As can be seen from the above, the tray 12 is used for holding the consumable grinding head 3 to be used, and similarly, the consumable grinding head 3 to be replaced can be also placed on the empty tray 12 for recycling after being detached from the wedging grooves 11.
Better, change the bistrique for consumptive material anchor clamps also can be used for snatching and carrying of tray 12, and is specific, press from both sides tray 12 through pneumatic finger and get then can carry tray 12, has removed the work of artifical transport tray from, reduces working strength.
The technical means disclosed by the scheme of the present invention is not limited to the technical means disclosed by the above embodiments, but also includes the technical scheme formed by the arbitrary combination of the above technical features. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also considered as the protection scope of the present invention.
